Motion detecting cat toy

We love our pets, but sometimes we just can’t keep up with them all the time. Sometimes, we need some automated playmates for our furry pals. [Kateham] has built a motion detecting cat toy to keep their cat content and active. Their price list was roughly $5 for the whole project, but they did obtain things like microcontrollers from family members. Some places they did manage to cut costs were to harvest various parts from a VHS deck. Its great to see kids not only hacking, but recycling as well. Great job [Kateham]. This project is like a simpler version of the laser pup.
